Why did Venus reverse and when did Venus appear?

We all know that Venus is one of the eight planets in the solar system, and it is also the second closest planet to the sun, and this planet is sometimes very close to the earth, but the temperature of Venus is the highest among the eight planets in the solar system, and in the eyes of scientists, Venus can be described as a real hell planet.

The biggest difference between Venus and the major planets is that the inclination angle of the rotation axis of Venus is different, that is, the inclination angle of the rotation axis of Venus and the major planets is different, which causes the reversal of the rotation of Venus.

If we regard the earth as a reference to Venus, if the earth's axis of rotation is inclined to the sun relative to the orbital plane of the earth's orbit, then for the inclination of the axis of rotation of Venus, the axis of rotation of Venus is deviated from the sun relative to the plane of the orbit of the revolution, due to the different inclination angles of the planets' axis of rotation, resulting in different gravitational distribution between the sun and the planets, such as Venus due to the inclination of the axis of rotation and the inclination of the earth's axis of rotation in the opposite direction, forming the position of the gravitational particle of the sun on Venus downward ( It is possible that Venus is above the orbital plane (North Pole)), and the gravitational attraction of the Sun on Venus is not perpendicular to the axis of rotation, but is inclined upwards (north) relative to the plane of orbit by 3° (the gravitational force of the Sun points to the south pole of Venus, pointing below the equator), so that the gravitational attraction of Venus (above the orbital plane) and the Sun and Venus is greatly weakened, but the gravitational attraction of Venus itself on the shady side is not weakened, but because the deviation of Venus's axis of rotation from the Sun tilts, the gravitational attraction of Venus in the shade of space increases. As a result, the shady resistance (air flow passing) of Venus is greater than that of the sunny side, and a rotational vortex opposite to the Earth is formed, and the rotation reversal of Venus is formed.

Many people have seen the brightest star next to the moon at this time of the yearThat isVenus. Because Venus is located in the Earth's orbit and sometimes appears in the early morning and sometimes at dusk, there is a saying for morning and evening stars. In the ancient books of our country, there is a saying that "there is Qiming in the east and Chang Gung in the west", which refers to Venus.

When Venus rises in the east before dawn, it is what we see and what we often call the morning star, and when it appears in the west at dusk, it is Chang Gung Star. But in ancient times, Venus at that time was called the Platinum Star.

Mankind's understanding of the solar system began with Venus. The Moon is about 380,000 kilometers away from Earth, while Venus is only 50,000 kilometers away. Venus is about the size of the Earth, with a mass of 82% of the Earth.

Because of the rotation of the earth and the rotation of the moon around the earth, it takes 225 days for Venus to revolve around the sun, so that when we look up at the starry sky on the earth, we will see that the moon moves faster than other planets, and when the moon moves near Venus, there is an astronomical phenomenon of "Venus with the moon". Venus is the neighbor of the Earth and is the brightest planet except for the Sun and the Moon. It's also a star that we can see with the naked eye.

When the Moon and Venus coincide, there is a phenomenon called "Venus conjunction the Moon". This astronomical phenomenon occurs every 30 days. Because of the distance of Venus, Venus is the brightest planet, and we can see this wonderful astronomical phenomenon with the Moon in most cases.

The phenomenon of Venus conjunct the moon because Venus is too close to the earth, the city is easy to be blocked by high-rise buildings, astronomy enthusiasts can choose to go to the open outdoors on a sunny day. The phone can capture the beautiful moments of the two together.

In ancient times, due to the lack of scientific understanding of the appearance of Venus and the moon, they believed that this phenomenon was a great omen, indicating a military disaster or human death. A lot of metaphysics came into being. With the improvement of the level of scientific development, human exploration of space is also increasing, completely breaking the saying that the meaning of Venus conjunction and the moon is ominous, but modern people have given a better meaning to the phenomenon of Venus with the moon than the ancients, and many people think that Venus with the moon is a symbol of love and romantic.

Venus and the moon are symbolized by modern people as cherishing the people in front of them, and many lovers will promise each other and make promises under the stars.

Analysis: We commonly use if ......, unless the sun comes out of the west to mean that something can't happen, because on Earth, the sun comes out of the east. This phrase must not be used on Venus, where the sun rises in the west and sets in the east.

This phenomenon is due to the fact that Venus rotates in the opposite direction to the Earth, with Venus turning from east to west and Earth turning from west to east.

The diameter of Venus is twice that of the Earth, and the density and size of the two are almost the same. For centuries, they were considered the sister planets of Earth. It was not until human beings explored and analyzed more deeply that they found that the surface environment of Venus was completely identical to that of the earth.

Venus also has an atmosphere on its surface, but more than 90% of it is carbon dioxide. In addition, Venus does not have an ocean (which has the effect of removing carbon dioxide), so that carbon dioxide continues to accumulate, causing a strong greenhouse effect. The surface temperature of Venus can reach 450 degrees Celsius, so Venus is very hot.

And the atmospheric pressure of Venus is 90 times that of the Earth, which is quite different from the Earth.

Venus's exterior is surrounded by thick clouds, which are mainly formed by sulfuric acid. More than 60% of the Earth's areas on Venus are relatively flat, and there are many mountains, basins, and canyons, similar to those of Earth.

Venus has a day and night of 243 days and an orbital period of 225 days. Venus's slow rotation is retrograde, meaning that it rotates from east to west, not west to east, as most planets do (Uranus also rotates retrograde, and Uranus' axis of rotation is tilted degrees, almost across the orbital plane). It is possible that this phenomenon was caused by the collision of Venus with other asteroids a long time ago, but it is not yet proven.

In addition to this unusual retrograde rotation, Venus is also a little unusual. Venus's rotation period is synchronized with its revolution, so that when the two planets are closest together, Venus always faces the Earth on the same side (once per Venus day). This may be the result of tidal locking, which affects Venus' rotation when two planets are close enough.

Of course, it is also possible that it is just a coincidence.

At the moment, scientists are unable to explain the phenomenon of Venus's reversal. However, there are two basic hypotheses, one is that Venus was reversed by the impact of a huge meteorite; The second is that there may have been some kind of drastic change in the inner core of Venus.

The earth itself does not rotate because the solar wind (i.e., strong light particles) pushes the gas, which drives the earth itself. The Moon does not rotate because there is no gas, and Jupiter rotates fast because there is more gas. The planet that is reversed is because it is too close to the sun (like the gears in a gearbox).

Got it?

It turns in the opposite direction and is incredibly slow, and the heat is incredibly high, and the volcano is very high! It was supposed to be caused by an asteroid collision!

Answer: The reason why Venus has lived so long is because of its special geography and chemical composition.

Explanation: Venus is one of the closest planets to Earth in the Solar System, and its density is similar to that of Earth, so it was once considered a sister star of Earth. However, the geochemical composition of Venus is very different.

Venus's atmosphere is mostly made up of carbon dioxide, which makes Venus's atmospheric pressure much higher than that of Earth. In addition, the surface temperature of Venus is extremely high, up to 470 °C, because the carbon dioxide and other greenhouse gases in Venus' atmosphere are able to effectively absorb and retain sunlight on the surface of Venus.

This special atmosphere and chemical composition allow Venus to survive in extreme environments. Because the atmospheric pressure of Venus is much higher than that of Earth, Venus's atmosphere can absorb and retain large amounts of solar energy, and there are still some microorganisms and other organisms on the surface of Venus. These organisms can survive by absorbing carbon dioxide and other chemicals from the atmosphere.

Expansion: Although the high temperature on the surface of Venus and the high pressure in the atmosphere make Venus an extremely hostile environment for life on Earth, the surface and atmosphere of Venus may be a suitable environment for some extremely thermophilic microorganisms. These microbes can survive by searching for nutrient substances on rocks or minerals on the surface of Venus, and photosynthesize by absorbing carbon dioxide from the atmosphere.

Therefore, Venus provides an interesting research direction for us to explore extraterrestrial life.

Answer: The reason why Venus has been able to live so long is because its core is made up of molten rock and metal, a composition that is capable of creating a strong gravitational pull that allows it to remain stable. In addition, Venus's thick atmosphere is also able to provide a degree of protection for it.

Explanation: Venus is the second-closest planet in the solar system to the Sun's terrestrial tremor, and its surface temperature is extremely high, reaching about 470. However, despite its harsh surface environment, Venus's internal structure is very stable.

Compared to other planets, the interior of Venus rarely experiences phenomena such as ** and volcanic eruptions, which can be attributed to its special composition.

Expansion: The internal structure of Venus can be divided into three parts: the core, the mantle, and the shell.

The core is made up of metals such as iron and nickel, the mantle is made up of rocks, and the outer crust is made up of silicate minerals. This structure allows Venus to generate a strong gravitational pull that keeps it stable. In addition, Venus also has a very dense atmosphere, which is one of the important reasons for its survival.

Venus, which appears in the western sky in the evening, is called Chang Gung Star, and the eastern sky in the morning is called the Morning Star.

Before and after the dawn, a particularly bright "morning star" is sometimes seen on the eastern horizon, it is not a light source, people call it "morning star"; And at dusk, a very bright "evening star" sometimes appears in the western afterglow, which is called "Chang Gung star".These two stars are actually one, Venus, which is called "Taibai" or "Taibai Star" in Chinese folkloreThe first morning star Venus comes out every night.

Because Venus is a mainland planet and its orbit is inside the Earth's orbit, it will either appear at dawn or in the evening. Now Venus appears in the evening. Venus is often mistaken for UFOs.

Venus is the brightest object in the night sky other than the Moon, because it is so bright that it leads quite a few people to think that it is not a star, and its brightness is far beyond the brightness of other stars we usually see (including stars and planets), and many, many people will say "definitely not a star" in a convincing tone, but it is a star. <>

Venus before dawn is less misidentified, because the average person has not yet gotten up, and the Venus that appears in the western sky at dusk is more misidentified, most people do not sleep, there are more people outside, more people see it, and there are more cases. Because Venus is very bright and there is no reliable reference at night, it is common to judge its distance very inaccurately when you see it, some of which are hundreds of meters. Every year, there are a large number of UFO cases of misidentification by Venus.

If you have some basic astronomical knowledge, you can judge it at that time, if you don't have the corresponding knowledge, if the weather is good the next day, you can continue to observe, or even observe it for several days in a row, and this bright object appears in the east of dawn or the west of dusk in the approximate time and approximate direction, and the object moves slowly and roughly westward with time, it should be Venus. 、

Venus is closer to the Sun, so we may see Venus in the west after the sun goes down or in the east before the sun comes out. Venus in the evening is called "Chang Gung", and Venus in the early morning is called "Qiming".

Venus, one of the nine planets of the solar system, is ranked second in order of distance from the Sun. In ancient China, it was called "Taibai Star".

Is Venus rotating in the opposite direction?

Why does Venus rotate in reverse?

Venus rotates from east to west, and other asteroids have hit Venus, reversing it.
